The lever is run upwardly on the bail until My improvement consists of a bail D, whose the central bend is reached. Then as soon as extremities are pivotally connected with the the closure or cap is applied to the jar or receptacle the bail is thrown downwardly to the locking position.

Having thus described my invention, what I claim is- 1. In a fastening device for the closures of receptacles, the combination of a bail whose extremities are pivotally connected with the body of the receptacle, and a lever provided with an opening through which the bail is passed whereby the bail becomes a fulcrum for the lever, the opening through which the bail passes being intermediate the arms of the lever, one arm of the lever being adapted to engage the closure and the other arm the bail when the lever is thrown to the locking position.

2. In a device of the class described, the combination with a receptacle and its closure, of a bail pivotally mounted on the body of the receptacle, a lever having an opening to receive the bail, an arm extending downwardly from the opening to engage the closure, and another arni extending beyond the opening and adapted to engage the bail when the lever is in the locking position.

8. The combination with a receptacle and its cap or closure, of a bail whose extremities are pivotally, connected with the receptacle and having an upward bend above the closure, and a lever threaded on the bail and having one arm engaging the cap and the other arm engaging the bail when the lever is in the locking position, the lever havingapart which engages the bend in the bail from below when the device is locked.

4. The combination with a receptacle and its closure, of a bail whose extremities are pivotally connected with the body of the receptacle, the bail having a central upward bend, and a lever having an opening intermediate its extremities through which the bail passes, the said lever having a part located adjacent the opening and adapted to engage the bend of the bail when the lever is thrown to the locking position, one arm of the lever projecting below the opening to engagement with the cap or closure, and the other arm projecting forwardly from the bend in the bail when the lever is in the locking position.

5. In a device of the class described, the combination with a receptacle and its closure, of a bail mounted on the body of the receptacle, and a locking-lever having an opening through which the bail passes, the bail serving to hold the lever in place, the lever extending lengthwise of the bail when in the locking position and having a groove in which the bail is received, substantially as described.

In testimony whereof I afiiix my signature in presence of two witnesses.

FRANK GANFIELD.
